There is one, for writing. For reading bytes, the CPU just reads a word and discards the upper byte. For writing, it asserts BWTBT and only the lower byte is written. -- Pete Peter Turnbull Network Manager University of York

XP1000 problems

by healyzh＠aracnet.com

Does anyone here know what the startup of a Compaq XP1000 (Alpha-based system for OpenVMS) is supposed to look like? I have an XP1000 with PowerStorm 300 and U2W-SCSI that I just received. It powers on, and all 8 diagnostic LED's light up. There are no beeps, and there is no video. I've tried to connect a VT420 to the serial ports using the cable for my PWS 433au, but have had no luck. I've tried reseting the CPU board, RAM, Video, and SCSI. Any suggestions would be appreciated. Thanks, Zane

By extention of this method, I should be able to count to 2097151. My wife, unfortunately for her, can count only to 1048575. :-) Ken

Apple Tape Backup 40SC

It is not very likely that you will find a working drive. Which version of the Microexplorer software do you have? There is at least one version which has been recovered.

It makes much more sense to talk base-2 about computer things, since computers operate base-2. Trying to force computer things to base-10 would be similar to walking around spouting base-7 numbers to people and expecting them to make sense of it. Although, base-2 counting of paces is useful. Once your "counter" rolls around to zero you've gone about a mile (2^10=1024 paces)

Apple Tape Backup 40SC

by mcwood＠nefkom.net

Good day, I would like to backup up some old Apple 1/4" qic tapes. I do have an "Apple Tape Backup 40SC" drive but the drive's rubber became soft. I already damaged 2 tapes so I would like to find someone who could borrow or sale his drive or read these tapes for me. What's on them ? Software for TI Microexplorer Lispmachines ! Greetings, Marc P.S.: I'm located in the south of Germany.

Not classic, but free: HP-UX

by compoobah＠valleyimplants.com

Just heard of a good deal from HP: they seem to be cleaning out the PA-RISC HP-UX B11.11 CD sets: you can get one free at : http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumbe… Not classic yet, although I suppose it will run on a few ontopic machines.

XP1000 problems

by mamcfadden＠cmh.edu

I just picked up 3 XP1000 boxes, then I found there were no CPU boards in them. I'm in Kansas City. 2 have disks, 1 has display card, they have PSU and CR-ROM drives Large power sink on motherboard made me think that was the CPU. I thought memory was under PSU. Imagine my suprise If anybody wants them they are yours for shipping. Thanks Mike

buying an Alpha Micro

by spectre＠floodgap.com

Today I was feeling nostalic for the old Alpha Micro I used to use, the first computer I actually hacked into manually (much to the dismay of the system administrator who then demanded to know how I did it). In particular I know it was a 68K AlphaMicro, probably an AM-1200. Is anyone getting rid of one of these, or knows someone who is? I found an Alpha Micro emulator and it's even Mac friendly but it just isn't the same as being in front of one of those amber terminals with an AMOS prompt. -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Had this been an actual emergency, we would have fled already. -------------
